My post above and your edits crossed each other.
The Traveler mod was just updated to full release a short while ago, v87 was fully released in Aug 2017. I had been using this version when it was in beta testing for eons and still have the full release now, as have many others. If you suspect it's the Traveler mod, then try downloading a fresh copy. Or you could opt to try the beta testing version v88 that became available just the other day though we've no reports of such crashing on either one.
I still have to ask if this is happening in only one world/ongoing save or if a new game behaves the same way. Or if you are clearing your scriptCache file, those seem to be the two remaining questions from the above.
For assistance with interpreting script error logs, that is a service we happily provide at NRaas. Can't really do that here.
